AURORA 81 is technically identical to the FinSteam Botnia gas sauna heater in terms of power output, gas consumption, and core performance. It is built on the same proven engineering platform, now enhanced with a new modern design.
The updated design makes AURORA 81 a better fit for permanent installations across a wide range of outdoor and ready-made saunas, including cube and barrel saunas. While it still works in tent saunas, its larger outer structure and expanded stone cage allow for nearly double the stone capacity compared to the traditional FinSteam Botnia 81 O model.
This increased stone volume significantly enhances the sauna experience, delivering richer, smoother, and more consistent Finnish löyly.
